Specification of Letters Patent.

Application filed March 13, 1905. Serial Nok 249.888.

T all whom it may concern:

Be it known that we, HENRY C. WILLIAM- soN and HERMAN PRIEs, citizens of the United States, and residents of Michigan City, county of Laporte, and State of Indiana, have invented certain new and useful Improvements in Underframing for Cars, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to underframing for cars in which the center sills are metal and to that type of car in which the body is low, the center line of draft being between the two center sills.

The object of the invention is to simplify and strengthen structures of this kind; and the invention consists in the parts and arrangement of parts as hereinafter described and as illustrated in the accompanying draw ings, in which- Figure 1 is a detail plan section of the framing of a car. Fig. 2 is a detail section on the line 2 2 of Fig. 1, andy Fig. 3 is a detail section on the line 3 3 of Fig. l.

There is shown at 10 portions of a pair of end sills, and at 11 11 the usual deadwood applied to the faces of these sills. The centersills 12 13 are metal and take the form of channel-beams having their flanges directed outwardly. These sills are continuous through the length of the car from points a little removed from the inner faces of the end sills. They are secured to the end sills through the medium of the cheek-plates 14 15, which are of usual and ordinary construction inthat they are provided with draftlugs, as 16 17, for the engagement of the followers 18 19. The draw-bar is shown at 20 and has the usual tail strap or loop 21 encircling the followers. Each of the cheekplates has a rearwardly-extending flange 22, which through portions of its length lies against the under face of the lower centersill flange and is riveted thereto. These flanges 22 at intervals extend downwardly to the lower edge of the cheek-plate, as shown at 23, providing seats 24, against which rest and to which are bolted the ends of the tie-plates 25, which unite the two cheek-plates and support the drawbar and followers. At its forward end each cheekplate has a vertical backwardly-extending flange 26, which lies against the inner face of the end sill and is bolted thereto, as shown at 27.

Fillet-ribs 28 extend from the inner face of the flange 26 and the outer face of the cheekplate, and their inner ends serve as an abutment for the web of the center sill. A horizontal flange 29 extends forwardly from the flange 26, adjacent its lower end, and bears against and is bolted to the lower face of the end sill, as shown at 30. The cheek-plates and center sills are united by rivets, as shown at 31, these rivets being as numerous as may be desired, and those located between the followers 18 19 are preferably countersunk at their inner ends in order that they may not interfere with the action of the usual springs (not shown) used in connection with this style of draft-rigging.

In practice the ends of the steel beams employed for the center sills as supplied to the car-builder are frequently not perfectly square; but by means of the structure herein shown and described a perfect fit for such a beam may easily be obtained by chipping with a cold-chisel the ends of one or both of the fillets 28 against which the end of the beam abuts.

We claim as our invention-- 1. In combination, a pair of cheek-plates each having a continuous longitudinal backwardly-projecting flange, such flange at intervals extending down to the bottom of the cheekeplate, a tie-plate seated against and riveted to the downwardly-extended portion of the flanges of both plates, and a center sill resting on the body portion of the flange of each plate.

2. In combination, a pair of metal center sills each having a backwardly-projecting bottom flange; a pair of cheek-plates each lying against the inner face of one of the sills and having a continuous longitudinal backwardly-projecting flange, such flange lying against the bottom flange ofthe sill and at intervals extending down to the bottom of the cheek-plate; and a tie-plate seated IOO against and riveted to such doWnWardly-eX- I against the supporting-fillets and riveted to tending portion of the flanges of both plates. the cheek-plates at each of its ends.

3. In combination, a pair of end sills; HENRY C. WILLIAMSON. cheek-plates having baekWardly-projeoting HERMAN PRIES. 5 vertical flanges lying against and bolted to Witnesses:

the end sills and having supporting-iillets; l NORTON W. BARKER,

and a' continuous inetal center silly abutting SAMUEL J. TAYLOR.,
